CMS Version: 4.5.1
Installation Method: Docker (official xibo-docker)
Operating System: Ubuntu Server 24.04 LTS
Issue:
Trying to connect a freshly installed self-hosted CMS 4.5.1 to Canva, following the standard integration steps (Application created with Authorisation Code, Is Confidential, correct redirect URI, full Sharing scope). The registration form ( Register | Xibo Canva Connector ) always returns:
“We have tried that address, but something is not right. Address not reachable”
I traced this at the reverse proxy access log level. The verification request from Canva’s backend does reach my server:
GET /about → 404 Not Found
User-Agent: GuzzleHttp/6.5.5 curl/7.74.0 PHP/8.2.31
I confirmed the 404 is coming from the CMS itself (Apache/PHP), not the proxy — same result curling /about directly on localhost, bypassing the reverse proxy entirely.
Given that 4.5 introduced a full frontend rewrite, I suspect the /about route may have been renamed or removed as part of that change, breaking the Canva connector’s reachability check.
Has anyone else hit this on 4.5.x? Any known workaround, or is this something the Canva connector needs updating for?
